Now this is ridiculous. Delmon Young, a prospect in Double A ball for the Tampa Bay Devil Rays threw his bat at an umpire. This video shows him getting thrown out of the game after arguing balls and strikes with the umpire. After he walks off the screen you see the ump toss him and almost immediately following you see his bat come flying into the screen and hit the umpire right by his head.

Talk about ruining your career with one mistake.
